This venerable circuit topology, essentially the simplest possible tube amplifier, has
reached almost cult status in today's audiophile circles. What is it about this circuit
that commands such a loyal following? Here is your opportunity to explore the possible
answers for yourself, at very reasonable cost. Even if you have to pay retail for all the
parts, the project should cost no more than about USD $100.

Interestingly, the euphonious nature of the Single-Ended Triode (SET) Amplifier can be
demonstrated even via mp3 files! A simple A/B comparison is available on the
Sound clips page.

This project is recommended for beginning vacuum-tube do-it-yourselfers. However, some previous
experience with building vacuum tube circuits is highly recommended. A very
basic electronics knowledge is assumed, as are the soldering and mechanical skills required
to assemble and wire the project. The information provided here is believed to be correct,
but the author and Dogstar Music assume no liability for damages incurred through use or
misuse of the information provided herein.

With the disclaimer out of the way, I can only add that this is the ideal project for exploring
the mystique of the single-ended triode amplifer. If you like the sound of the SET topology, you
just might find yourself using the MiniBlok as a warmup for a larger project. If not, you haven't
invested much, and might still find MiniBlok useful as a "center-channel" fill-in
amplifier to add some depth and colour to your stereo system.

answering questions covered in the article, I'd be happy to help out with any concerns not
adequately addressed on this site.
